Only this appears...
Ahh sorry, yes, just check back last page, must have missed that one.
Annoying really, fully blocked.
It has to do with the cors restriction you showed in the console.
Most likely when you export the game to html and place it on the same server as the php file, it will work.
There are some options to disable the cors problem here, one of them could be creating a new shortcut on your desktop for chrome and add "--disable-web-security" at the end. Though, its not an advisable method to surf around with.
Sometimes impropper configured headers can cause similair situations, but here its simply the default security of you getting information from a different domain then from where the app or page your request originated from.
